Abstract: 341,497. Turning. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Warner & Swasey Co. ; 5701, Carnegie Avenue, Cleveland, Ohio, U.S.A.) Aug. 15, 1929, No. 24911. [Class 83 (iii).] A lathe or like machine having a saddle with a cross-slide thereon has a second slide movable in any direction on the cross-slide and traversing means for both slides which may be operated by hand or power. The cross-slide and second slide, together with their traversing means may be formed as an attachment for an existing saddle. The cross-slide 21 is mounted on a dovetailed guide 22 of the saddle 12 which slides on ways 14 on the bed 10 and carries the usual apron 13 containing the traversing gears driven from a longitudinal splined shaft on the bed. The second slide 23 carrying a tool-turret 24 or other tool holder is slidable along a dovetailed guide 27 on a turntable 28 having a circular projection 28a entering a recess in the slide 21. Bolts coacting with a circular T-slot in the table 28 serve to lock the guide 27 in any angular position. A splined shaft 31, Fig. 2, is rotatably mounted in the slide 21 and carries a keyed pinion 32 located between shoulders 12a, 12b, on the saddle and engaging the usual gear 33 in the apron which may be connected by a hand-controlled clutch 34 to the longitudinal feed shaft. A gear 37 is axially movable on the shaft 31 by a hand-operated plunger having three locating notches co-operating with a spring detent, the gear being caused to engage either of two gears 41, Fig. 2, or 52, Fig. 3, or to occupy a neutral position. The gear 41 is secured to a feed screw 40 rotatable in the slide 21 and engaging a nut 42 secured to the saddle and the gear 52, which is carried by a short shaft 51, drives a gear 53 on a shaft 44 rotatable in the slide 21 and having a worm thereon meshing with a worm wheel 46 on a vertical spindle 47. The spindle 47 is at the centre of rotation of the turntable 28 and carries a pinion 49 engaging a rack 50 on the second slide 23 to feed the latter in any of its angular positions. The screw 40 and the shaft 51 have squared ends for hand rotation and are arranged close together to facilitate simultaneous control of the slides 21 and 23. Graduated collars 54 secured to the screw and shaft carry adjustable spring clip indicators 55 and cooperate with zero marks on the slide 21. The front part 35 of the slide 21 is preferably made separate therefrom as shown and carries the bearings for shafts 31, 40, 44 and 51, whilst a plate 36 secured thereto provides a thrust bearing for collars 31a, Fig. 2, on the shafts 31 and 40. To adapt the saddle for a single cross-slide the shaft 31 is replaced by a screw such as 40 and the nut 42 is inverted so as to project into the recess 421.

Title: Improvements in or relating to automatic draft regulating devices for the drawing sections of textile spinning machines or preparatory machines
IPC: D01H5/42
Filed: 1959-07-21
Abstract: 891,321. Drafting-mechanism. VENNER, H. A. L. (Spinnereimaschinenbau Karl-Marx- Stadt VEB). July 21, 1959, No. 25007/59. Class 120(2) [Also in Group XXXVIII] Means for automatically regulating the draft according to variations in sliver-thickness and delaying the regulation until that portion of the sliver giving rise to it reaches the drafting field, comprises three potentiometers, two 12, 13 in series and one, 14, in parallel with them, 12, 13 forming one side and 14 the other of a switching bridge for a reversible electric motor 16 which initiates the regulation: the potentiometer 12 is adjustable by one of two sensing-rollers 5, 6, while 13 is manually adjustable according to the basic speed of the driving roller 5 of the sensing- pair suitably to delay the effect of the regulation, and is coupled to a voltage adjuster 19 for the motor, the latter also constituting the adjusting means for the potentiometer 14. Displacement of roller 6 rotates a gear 11 through a quadrant 10 and a pivoted lever 8: the gear 11 adjusts the setting of potentiometer 12 and if the bridge is unbalanced current flows through a polarized relay 15 to close one of two contact-pairs governing motor 16. The arm of potentiometer 13 is coupled to the arm of a votage-adjuster 19 which, through a rectifier 24, feeds motor 16 which is coupled to the arm of potentiometer 14 to move it until there is equilibrium in the bridge to cut-off current to the motor. The latter also acts to vary the output of one of two hydrogenerators 36, 37, the latter of which supplies through a valve 39 two hydromotors 26, 25 coupled respectively to the back and front rollers 2, 1 of the drafting -frame, the latter coupling being through lower roller 5 of the sensing-pair and a chain 35. Valve 39 supplies part of the driving fluid to motor 26 and part to 25. The return line 48 from motor 26 is the output line of generator 36, the output of which accordingly brakes motor 26 to a greater or less degree. If motor 26 decelerates, motor 25 accelerates on account of valve 39. A safety valve 49 and a pressure-holding valve 53 are provided while a pump relieves hydromotor 37 from having to draw up the driving-fluid. The arrangement can be adapted to drive either the front or the back rollers.

IPC: F16D33/16
Filed: 1958-08-11
Abstract: 847,742. Hydraulic couplings. TWIN DISC CLUTCH CO. Aug. 11, 1958, No. 25729/58. Class 69 (2). The filling of an hydraulic coupling 12 having its output 15 connectible to a load, such as a conveyer, and its input connected to an electric motor 10 is limited during the starting period of the load from rest to rated speed by a valve 23 biased to a first position, wherein it connects the outlet 22 from a pump 20 to a sump 18, and shiftable to a second position wherein it connects the outlet to the coupling which is provided with apertures 16, 16a to substantially empty the coupling when at rest, an electric power sensing means 33, responsive to the power demands of the motor, triggering a device 41 at a predetermined response to effect a return of the valve 23 to the sump-connecting position. The coupling has axially-spaced facing impellers 13 which are connected to a shaft 11 driven by the motor 10, by a chain drive 21 to the pump 20, and co-operate with oppositely facing runners 14 connected to the output shaft 15. Fluid from the sump 18 passes through a pipe 19 to the pump connected by a pipe 22 to the valve movable by a solenoid 49 against a spring 52 to disconnect the output of the pump from the sump and connect it to a pipe 28 leading to the input of the coupling; a thermostatically controlled valve 29 is provided to by-pass the fluid through a cooler 30 if the temperature of the fluid reaches a predetermined value. The solenoid 49 is controlled by a relay 41, the coil of which is connected to a contact 37 arranged to be engaged by a second contact 36 on the needle of the sensing device 33 which is in the form of a wattmeter, a coil on the needle of the wattmeter bridging the power lines 30, 31 from a starter 32 to the motor, the starter also being connected to the circuit of the solenoid 49. In operation with the load at rest, the motor at rest and the coupling substantially empty, the starter is operated to connect the motor to the power lines and energize the solenoid 49 to position the valve and connect the output from the pump to the coupling. As the coupling fills and accelerates the load, the torque on the motor increases and the needle of the wattmeter moves to connect the contacts 36, 37 which energize the relay 41 which, in turn, deenergizes the solenoid 49 to connect the output from the pump to the sump. The expelling of fluid from the coupling through the apertures 16, 16a decreases the torque on the motor and the wattmeter operates to re-energize the solenoid and re-connect the pump to the coupling. This cycle is repeated until the load is running at the rated speed and the pump then continuously supplies fluid to the coupling.
